expand sqrt((m^2-n^2)^2+2mn)

expand

(m^{2} - n^{2})^{2} + 2 mn

m^{4} - 2 m^{2} n^{2} + n^{4} + 2 mn

Solution steps

(m^{2} - n^{2})^{2} + 2 mn

Expand

(m^{2} - n^{2})^{2} + 2 mn : m^{4} - 2 m^{2} n^{2} + n^{4} + 2 mn

= m^{4} - 2 m^{2} n^{2} + n^{4} + 2 mn

\frac{( - 1 - 2 x ) ( 3 - 2 x ^{2} )}{3}

(2, - 7) y (- 4, 11)

e^{y} (y - 1)

(e^{\frac{y}{4}} + 6)^{2}

\frac{12 s + 57}{( s + 2 ) ( s + 4 )}
